---------------------------------
Summary: KafkaConsumer.subscribe() override that takes just
Pattern without ConsumerRebalanceListener
Key: KAFKA-5726
URL: https://issues.apache.org/jira/browse/KAFKA-5726
Project: Kafka
Issue Type: Improvement
Components: consumer
Affects Versions: 0.11.0.0
Reporter: Yeva Byzek
Priority: Minor
Request: provide {{subscribe(Pattern pattern)}} override, similar to
{{subscribe(Collection<String> topics)}},
Today, for a consumer to subscribe to topics based on a regular expression
(i.e. {{Pattern}}), the only method option also requires to pass in a
{{ConsumerRebalanceListener}}. This is not user-friendly to require this second
argument. It seems {{new NoOpConsumerRebalanceListener()}} has to be used.
Use case: multi datacenter, allowing easier subscription to multiple topics
prefixed with datacenter names, just by using a pattern subscription.
